Expanding into the New Zealand electricity retail market? The broad contours of the New Zealand system

Last week, New Zealand’s electricity regulator announced that “consumer choice has reached record levels, with 47 different retail brands now supplying New Zealand households”.[1] With so many new entrants into the New Zealand retail market (12 in the last year), it is worth taking a look the general features of the New Zealand electricity system and retail market and how they contrast with Australia’s.

  1. The New Zealand grid and wholesale market

As in Australia, the retail market has been traditionally dominated by several ‘gentailers’, vertically integrated organisations with separate generation and retail arms. Five gentailers, Contact Energy, Genesis Energy, Mercury Energy, Meridian Energy and TrustPower together produce about 95% of New Zealand’s electricity.

Also as in Australia, generation, transmission, distribution, retailing and market operation are distinctly regulated roles and functions. In the Australian National Energy Market (NEM), offers from generators are settled in an independently operated wholesale spot market. In New Zealand, Transpower (who is also the owner of the transmission network) is the physical system operator. A group of private entities contracted to provide expert market operation roles such as ‘Pricing Manager’, ‘Clearing Manager’ and ‘Reconciliation Manager’.[2]

Sitting alongside the wholesale market are derivatives markets (both ‘over-the-counter’ and exchange-traded) to enable hedging. As in the NEM, a tome of mandatory rules governs the operation of the wholesale market and the roles of participants: The Electricity Industry Participation Code (the Code) is New Zealand’s version of the Australian National Electricity Rules.

Overseeing the system is the regulator, the Electricity Authority, which is analogous to a hybrid of the Australian Energy Regulator and Australian Energy Market Commission in that it both sets the rules for market participants and monitors compliance.

  1. Differences in retail regulation between Australia and New Zealand

One very clear regulatory difference between the New Zealand electricity system and Australia’s, are the rules governing retailers. Overall, retail regulation in New Zealand is far less prescriptive, with few mandatory obligations specifically for electricity retailers. While there are some obligations for retailers set out in the Code (such as the requirement to compensate customers in some circumstances), and protections from general consumer law, New Zealand does not have a mandatory set of rules governing retail rights and obligations analogous to Australia’s National Energy Retail Rules. In its place, New Zealand has a set of voluntary guidance including:

Furthermore, unlike some Australian states, there are no standard contract offers with regulated (or ‘notified’) prices. Note, however, that retailers are required to provide customers with ‘low fixed charge tariff’ options of no more than 30c per day for customers that consume less than 8,000kWh (or 9,000kWh in certain parts of the South Island). Customers who take up this option then pay a higher variable charge than they otherwise would.[3]

Furthermore, generous Government subsidies direct to consumers go some way to achieving the same end as price regulation, such as the recently announced ‘Winter Energy Payment’. This will provide up to $700 a year for superannuitants and those on benefits for the payment of electricity bills.[4]

  1. Challenges for the New Zealand Market

As in Australia, surging electricity prices for consumers are a major concern. Earlier this year, the new Labour-NZ First Coalition Government announced a wide-ranging review of the electricity system. This comes off the back of an International Energy Agency (IEA) Report that showed that power prices in New Zealand had risen 50 percent since 2000 with consumers paying some of the highest rates across the IEA countries.[5] The review will consider, among other things, whether the ‘low fixed charge’ tariff and ‘Winter Energy Payment’ adequately target those in need.

One historic controversy, which may arise once more through this review, is whether the domination of so few generators in the market has lead to those generators exercising ‘market power’ to maximise profits, including withholding power at peak times.[6] Another issue that may arise, in some guise, is the former Labour policy of ‘NZ Power’ – a single buyer of electricity from the wholesale market aimed at cutting costs for consumers.[7]

Avoiding Compliance Atrophy: The Critical Role of Assurance Reviews for Growing Energy Retailers

As energy retailers expand their customer base and operations, ensuring ongoing compliance with regulatory obligations can become increasingly challenging. A key risk is “compliance atrophy” – where initially compliant documents, processes and systems slowly deteriorate and waste away over time if not regularly monitored and reviewed. What is compliance atrophy? Compliance atrophy is typically a result of documents, processes and systems being ‘updated’ or ‘reworded’ to reflect changes in focus for the business and input from other stakeholders including marketing

AER payment difficulty framework review

The Australian Energy Regulator (AER) is conducting a review of the consumer protections available under the National Energy Customer Framework (NECF) for those experiencing payment difficulties. On 14 May 2024, the AER released an issues paper for consultation. The review is driven by the commitment in Action 8 of the ‘Towards Energy Equity’ strategy in which the AER committed to considering whether improvements could be made to the NECF to ensure that consumers experiencing payment difficulties are identified early, engaged

Compliance Quarter’s Submission to the AER’s Review of the Compliance Procedures and Guidelines

On 11 April 2024, Compliance Quarter put forward its submission on proposed changes to the AER Compliance Procedures and Guidelines. The AER is reviewing its Compliance procedures and guidelines, which set out the manner and form in which energy businesses in jurisdictions that have adopted the National Energy Retail Law must submit compliance information and data to the AER. We argue that there should be consideration of measures to incentivise early reporting of potential breaches. These may, for example, take the
